        abstract = {Farmers rely on cost-effective refrigeration technologies, which are crucial for preserving crops and preventing spoilage. This study aims to enhance refrigerator efficiency by modifying an adiabatic capillary tube. Experiments were conducted using different capillary tube diameters—0.031", 0.036", and 0.040"—with R134a and R600a refrigerants. The results showed that the 0.031" diameter tube achieved faster cooling due to a quicker pressure drop. Optimal performance was observed with a 40 mm coil diameter, outperforming both 60 mm and elliptical coils. Increasing the tube diameter from 0.031" to 0.040" led to an 8% increase in the coefficient of performance (COP) due to reduced pressure and compressor workload. The combination of a 0.040" diameter tube with a 40 mm coil diameter yielded the highest COP. With a 40% reduction in mass charge, R600a demonstrated a 46% improvement in refrigeration efficiency over R134a, attributed to its superior heat absorption and lower operating pressures, making it more effective for cooling.},
